We divide 49369391 by 257
The aim is to understand the frequency of 257 in 49369391.

Advancing to step 1:
If we divide 4 by 257, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 257

Moving on to step 2:
257 goes into 49 0 times with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 257

Advancing to step 3:
493 divided by 257 is 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 257 from 493 leaves us with 236.
Include the next digit (6) from the dividend after 236, then repeat: 2366 / 257

Advancing to step 4:
257 goes into 2366 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 2313 from 2366 and we're left with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 257

Step 5:
When dividing 539 by 257, we get 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 192.0
Subtracting 514 from 539 leaves us with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 257

Moving on to step 6:
When dividing 253 by 257, we get 0 with a remainder of 253.
The next digit of our result is 0. 
Result so far: 1920.0
The remainder is 253 after subtracting 0 from 253.
Fetch the next digit (9) from the dividend, attach it to 253 and continue: 2539 / 257

On to step 7:
The number 257 fits into 2539 9 times, leaving a remainder of 226.
The number 9 becomes the next digit in our result. 
Result so far: 19209.0
Subtracting 2313 from 2539 leaves us with 226.
Bring next digit (1) of the dividend behind the 226 and repeat the process: 2261 / 257

Moving on to step 8:
When dividing 2261 by 257, we get 8 with a remainder of 205.
The next digit of our result is 8. 
Result so far: 192098.0
Subtracting 2056 from 2261 leaves us with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 9:
When dividing 2050 by 257, we get 7 with a remainder of 251.
Put 7 as the next digit of the answer. 
Result so far: 192098.7
If we take 1799 away from 2050, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 10:
If we divide 2510 by 257, we get 9 and a remainder of 197.
Put 9 as the next digit of the answer. 
Result so far: 192098.79
Subtract 2313 from 2510 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 11:
When dividing 1970 by 257, we get 7 with a remainder of 171.
The number 7 becomes the next digit in our result. 
Result so far: 192098.797
The remainder is 171 after subtracting 1799 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Step 12:
257 can be fit into 1710 6 times, resulting in a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 192098.7976
If we subtract 1542 from 1710, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 13:
257 can be fit into 1680 6 times, resulting in a remainder of 138.
The next digit of our result is 6. 
Result so far: 192098.79766
Subtract 1542 from 1680 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final outcome is 192098.79766, with a leftover of 0.000138.
